NVIDIA has issued a vital safety replace to deal with a high-severity vulnerability found within the NVIDIA® Container Toolkit for Linux.
The flaw, tracked as CVE-2025-23359, may enable attackers to take advantage of a time-of-check time-of-use (TOCTOU) vulnerability to achieve unauthorized entry to the host file system.
This vulnerability may probably result in code execution, denial of service, privilege escalation, information tampering, and knowledge disclosure.
Particulars of the Vulnerability
The vulnerability, affecting all variations of the NVIDIA Container Toolkit as much as 1.17.3 and NVIDIA GPU Operator as much as 24.9.1, has been assigned a CVSS v3.1 base rating of 8.3 (Excessive).
Utilizing a specifically crafted container picture, attackers can exploit this flaw to govern the container runtime setting, compromising the host system.
Influence
- CWE-367: The vulnerability stems from an insecure dealing with construction in recordsdata, permitting attackers to bypass default safeguards.
- Potential Penalties: Code execution, system crashes, elevated privileges, information publicity, and tampering.
NVIDIA acknowledges that the true threat will depend on particular configurations, emphasizing the significance of evaluating your techniques individually.
Safety Patches and Mitigation
NVIDIA has launched mounted variations of its software program to remediate the problem:
- Container Toolkit: Up to date to model 1.17.4
- GPU Operator: Up to date to model 24.9.2
Customers are suggested to obtain and set up the up to date variations as per the directions within the official NVIDIA documentation. Failure to replace might depart techniques susceptible to exploitation.
The patch alters the default habits of the NVIDIA Container Toolkit. CUDA compatibility libraries inside containers are not robotically mounted to the default library path.
Whereas this transformation enhances safety, it could disrupt some purposes reliant on earlier habits.
For customers requiring the legacy setup, NVIDIA has launched a characteristic flag, allow-cuda-compat-libs-from-container, to opt-in.
Nevertheless, NVIDIA strongly advises in opposition to utilizing this flag because it reintroduces the vulnerability.
For purposes depending on CUDA ahead compatibility, customers can manually configure the LD_LIBRARY_PATH to incorporate /usr/native/cuda/compat.
This workaround, nonetheless, might pose portability challenges when utilizing completely different driver variations.
This vulnerability was disclosed by Andres Riancho, Ronen Shustin, and Shir Tamari from Wiz Analysis, together with Lei Wang, who independently reported it.
NVIDIA encourages customers to remain knowledgeable by subscribing to their Product Safety bulletins for the newest updates and steerage.
With threats on the rise, making certain immediate updates and proactive safety administration is essential to sustaining system integrity.
